SPECIFICATION forming part of Letters Patent No. 502,278,

dated August 1, 1893.

Application filed May 1, 1893. Serial No. 472,572. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES EDWARD BUT- LER,

State of Maryland, have invented certain new and useful Improvements inDumping- Wagons; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates especially to dumping wagons for use in cities fordelivering coal, wood, and the like, where it is desired to dump thematerial directly into the cellar, vault or bin.

The object of the invention is to provide a wagon of this characterwhich shall be strong and durable in construction without being heavyand cumbersome, and wherein the dumping mechanism shall be simple andeasily understood and operated.

The invention consists in the construction, arrangement, and combinationof parts hereinafter described and claimed, and illustrated in theaccompanying drawings'forming part of this specification, wherein Figure1 is a side elevation of the wagon in position to receive its load. Fig.2 is a front end elevation of the same, also in position for loading,and Fig. 3 is an elevation similar to Fig. 1, except that the wagon bodyis shown in different positions for discharging its load.

Referring to these views, 1 is the truck, which may be of any desiredconstruction. It is preferably set higher in front than be hind, asshown, but this is not essential. 2 is the wagon body. This may also beof any desired form or construction, the invention not being limited toany particular specific con- The body is connected to the truck by meansof pivoted links 3, of which there is one pair at or near the front endand another pair at the rear, as clearly shown in Figs. 2 and 3.

On either side of the body, standards l are erected, these standardsextending to apoint considerably above the body and somewhat back fromthe center. Journaled in suitable bearings at or near the upper ends ofthe standards is a Windlass shaft 5, having cona citizen of the UnitedStates, residing at St. Michaels, in the county of Talbot and nectedthereto the upper ends of ropes or chains 6, which extend down and arefastened to either side of the wagon body, preferably a little forwardof the vertical plane of the Windlass shaft.- A ratchet disk 7 isrigidly fixed to one end of the shaft 5, and a hand operating lever 8 ispivotally mounted on the standards in suitable proximity to the disk,being preferably pivoted on an extension of the axis of the shaft. Thishand lever is pivoted at a point betweenits ends, as shown, and

carrieson its upper end a pivoted operating dog or pawl 9, which isadapted to normally engage the teeth of the ratchet 7.

p 10 denotes a weighted holding pawl pivoted on the standard and adaptedto engage the ratchet on the opposite side from the operating dog. Ahook 11 is hung on the adjoining timber of the standard, the object ofwhich is to engage the 10 and hold it out of engagement so as to permitthe body to be lowered.

The hand lever 8 is provided with means whereby the operator may releasethe operating dog 9 and hold it out of engagement with the ratchet 7.This mechanism consists of a rod 12 sliding in guide keepers or stapleson the handle, and having its upper end bent at an angle, as shown inFig. 2, and arranged to underlie the dog 9. The lower end of the rod 2is also preferably bent so as to form a hold for the fingers.

As illustrated in Fig, 3, the links at the front end of the body areconsiderably longer than those at the rear. The object of thisarrangement is to enable the body to be tilted more or less for thepurpose of automatically discharging its load. As before described, thepoint of connection of the chains with the body is forward of thevertical plane of the Windlass shaft. The object of this arrangement isto carry the body over past the dead center of the rear links, so thatthe weight of the body and its load will continue the rearward movement.

The construction being as above described, the operation is as follows:The body being in the position indicated in Fig. 1, and, it beingdesired to dump the load, the operator taking hold of the hand leverturns the shaft with a stepby-step movement until the body has beenraised into the position shown in lower end of the pawl full lines inFig. 3. If the mouth of the cellar or vault is near the curb, it willnot be necessary to continue the movement of the body, but the loadmaybe discharged in this position by simply raising the tail board. If,however, the cellar, opening, orpoint at which the load is bedischarged, is farther removed from the curb or gutter, the operator byreleasing the holding pawl may permit the loaded body to descend intothe posltion shown in dotted lines, when the load may be discharged inthe same way, but at a point farther removed from thewheels. The objectof the mechanism carried by the hand lever for throwing out theoperating pawl, is to enable the body when unloaded and lifted into theposition shown in Fig. 3 to return by its own weight to its normalposition easily and quickly without having to work the lever.

It will be understood that this construction dispenses with the heavyand complicated gearing underneath the truck, which is so common inthese dumping wagons; also that, by the employment of an overheadWindlass and chain, all props and lifting levers between the trnck andthe wagon body are dispensed with. A further advantage arising from theuse of the overhead Windlass in conjunction with the pivoted linksbeneath the body, is that it permits the shifting of the body lengthwiseinto various positions within wide limits, thus allowing the load to bedelivered at a point farther in the rear than is possible with any ofthe other wagons not employing separate chutes or spouts.

Having thus described my invention, what I claim is- 1. In a dumpingwagon, the combination of the truck, the standards on the sides, the

body connected to the truck by pivoted links, the Windlass shaftjonrnaled in the standards above the body, and the chains connecting theshaft with the body, substantially as described.

2. In a dumping wagon, the combination of the truck, the standards onthe sides, the body connected to the truck by pivoted links, theWindlass shaft journaled in the standards above the body, the chainsconnecting the shaft with the body, the operating lever, and the holdingpawl; substantially as described.

3. In a dumping wagon, the combination of the truck, the standards onthe sides, the body connected to the truck by pivoted links, theWindlass shaft journaled in the standards above the body, the ratchetdisk on the shaft, the chains connecting the shaft with the body, theoperating lever, the releasable pawl carried by the lever, and theholding pawl, substantially as described.

4. The combination of the Windlass shaft, the ratchet disk fast thereon,the operating lever, the pawl carried by the lever, mechanism carried bythe lever for releasing the pawl at will, and the holding pawl,substantially as described.

5. In a dumping wagon, the combination of the truck, the body, thepivoted links connecting the body to the truck, the front links bein glonger than those at the rear, and the overhead raising and loweringmechanism, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES EDWARD BUTLER.
